These two sailing ship papercraft were created by the Atocha Treasure Company. On the left is the Spanish galleon Nuetstra Senora De Atocha which sank in a hurricane off the coast of Florida in 1622. Modern treasure hunters were able to locate the wreckage and salvage the Atocha's treasure in 1985. On the right is a generic model of a buccaneer pirate ship from the same time period as the Atocha. A low-res sample template for the galleon is posted here while a low-res sample template for the pirate ship is posted here. Pre-printed, high resolution templates may be ordered from the ATC for a price.
UPDATE 3/1/2015: Pre-printed hi-res templates are no longer offered by ATC. In fact, the ATC paper model website no longer exists. The links to the low-res versions now point to alternate locations where images of the templates have been preserved.
